Understand that a right angle is an angle that measures exactly 90 degrees.
Review the given options: 10°, 90°, 180°, and 50°.
Recall the definition of standard position: an angle drawn with its vertex at the origin and its initial side along the positive x-axis.
Identify which of the given angles measures exactly 90°, since that is the measure of a right angle.
Conclude that the angle measuring 90° is the right angle in standard position.
